Determining type of drive a file is on

[kee nethery]

How about:
Get a list of all the attached volumes, names and sizes
See if the USB drive that you initialized is visible and see if it is 
the same size as what you configured it to be.
Then see that you are running from that volume.
Not fool proof but it's a start.
If you have a way to read a specific block on the drive, you could use 
that data to provide yet another check. Put a tiny 1K file on the 
drive, add your file to the drive. Delete the 1K file. It will look 
like there is just your drive but if they duplicate the whole thing to 
another USB key, that 1K blank space won't be there.
